The Single Rental Registry — popularly known as the NRUA, from its Spanish initials — was, for barely ten months, the centrepiece of State control over short-term and seasonal rentals in Spain. Created to transpose an EU rule, Royal Decree 1312/2024 required, from 1 July 2025, a registration number before any short-term accommodation could be advertised on digital platforms. On 19 May 2026, the Supreme Court annulled the State procedure for encroaching on regional competences. This guide explains what the NRUA was, what has fallen, what remains in force, and what an owner or manager should do in the current situation.

What is the Single Rental Registry?

The Single Rental Registry was the State procedure, run through the Land Registrars and Registrars of Movable Property, under which an owner or landlord had to apply for a unique identification number for each property intended for short-term letting — tourist or seasonal — before it could be advertised on digital platforms that allowed booking and payment online, such as Airbnb, Booking, Vrbo or Expedia. Once granted, that number was recorded as a marginal note on the property's land registry entry.

The registry did not cover tourist rentals alone: it also reached seasonal rentals — for study, work or medical reasons — when arranged through an online platform with remote payment, which considerably widened its practical scope compared with pre-existing regional tourism rules.

The EU origin: Regulation (EU) 2024/1028

The Spanish rule did not arise on its own. It transposed Regulation (EU) 2024/1028 of the European Parliament and of the Council, of 11 April 2024, which set harmonised rules for collecting and sharing data on short-term accommodation rental services across the Union. Its stated aim was to improve the information available to public authorities and ensure fair competition between platforms and accommodation providers.

One nuance proved decisive in the litigation that followed: the EU Regulation does not require Member States to create a national registry. It only requires that, where a Member State already has registration procedures for this type of accommodation, a Digital Single Window be set up to centralise data exchange with platforms. Spain already had registration procedures in place — but at regional, not State, level.

Royal Decree 1312/2024: how the NRUA worked

Royal Decree 1312/2024, of 23 December, published in the BOE on 24 December 2024, entered into force on 2 January 2025 and became effective on 1 July 2025, after a period allowed for technical adaptation. It created two distinct tools that should not be confused:

  • The Single Rental Registry procedure, which required each property to be registered and an NRUA number obtained as a precondition for advertising it on online platforms.
  • The Digital Single Window for Rentals, attached to the Ministry of Housing and Urban Agenda, conceived as the channel for exchanging data between platforms and the authorities.

Who had to apply for it

Landlords — whether professional or private individuals — wishing to offer short-term accommodation, tourist or otherwise, through online platforms allowing remote booking and payment had to obtain the NRUA. Without the number, the rule expressly prohibited marketing the property on those platforms.

What data the procedure required

The application required identifying the property owner, the cadastral reference and exact address, the type of tenancy — holiday or tourist, work, study, medical reasons or other — and other data that then had to be reported annually to the authorities through an information return approved by ministerial order.

Important:

The specific penalty regime under Royal Decree 1312/2024 was never actually developed. The rule itself provided that, until it was approved, the existing State, regional and local penalty regimes would apply — which in practice meant each region's own tourism rules.

The Supreme Court judgment that annulled the State registry

The Generalitat Valenciana challenged Royal Decree 1312/2024 before the Supreme Court, joined by other regional governments and industry associations. The core argument: tourist rentals and tourism policy are a regional competence, and the State could not impose a national registry that overlapped with the tourist-accommodation registries already in place in each region.

The Administrative Chamber of the Supreme Court, in Judgment No. 620/2026, of 19 May 2026, partially upheld the appeal and declared void the provisions of Royal Decree 1312/2024 specifically concerning the single registration procedure and the obligation to register in order to obtain the number needed to advertise the property. The annulled provisions substantially include:

  • Article 1, as regards the development of the Single Rental Registry procedure.
  • Article 2, points (f), (i) and (j), which defined the procedure, the registration number and the competent registration authority.
  • Article 5, governing the obligations of landlords linked to the registry.
  • Article 6, only as regards references to the single registration procedure and the registration number — not in its entirety, as the Supreme Court itself later clarified.
  • Articles 8 to 10 and Article 12, points (b) and (c), together with the second additional provision and certain references in the first final provision.

The ruling rests on the finding that the competence titles invoked by the State — civil legislation and the organisation of registries and public instruments — were insufficient to justify a comprehensive national registry in a field, tourism and housing, that is largely a regional competence.

What this means in practice:

From the publication of the judgment in the BOE, the State Single Rental Registry procedure and the linked NRUA number are no longer required. No platform or authority can any longer condition the publication of a listing on holding that State number.

What remains in force after the judgment

The annulment is partial and should not be read as the disappearance of the entire regulatory framework. The following remain fully in force:

  • The Digital Single Window for Rentals, as the technical infrastructure run by the Ministry of Housing and Urban Agenda.
  • The obligations on online platforms to transmit booking and host data to the authorities under Regulation (EU) 2024/1028, insofar as this does not depend on the annulled registration procedure.
  • The regional tourism registers and licences — VUT, VFT, HUTB, ETV, depending on the region — which remain the real title that authorises operating a short-term rental.
  • Municipal planning obligations, the habitability certificate, guest registration with the competent police force — the Mossos d'Esquadra in Catalonia, SES Hospedajes elsewhere in Spain — and tax obligations, including the informative return under form 179 and, for platforms, form 238.
  • The regime under Article 17.12 of the Horizontal Property Law, introduced by Organic Law 1/2025, which requires a three-fifths majority to authorise tourist activity in a building under horizontal property.

In other words: the centralised State census falls, but none of the tourism, planning, tax or horizontal-property obligations that already existed before Royal Decree 1312/2024 fall with it.

Effects in Catalonia and Barcelona

In Catalonia, the annulment of the NRUA does not change the regime applicable to short-term tourist accommodation (HUT/HUTB), which still requires a municipal licence, registration with the Registre de Turisme de Catalunya, and, in Barcelona, compliance with PEUAT zoning. Anyone who already met these requirements sees no change as a result of the Supreme Court judgment; anyone who relied solely on the NRUA number without holding the corresponding regional tourism authorisation remains — and always was — in an irregular position vis-à-vis the Generalitat and the City Council.

It is also worth remembering that Barcelona adds its own additional layer: the announced non-renewal of HUTB licences once they expire, with a horizon of November 2028. Full details can be found in our PEUAT Barcelona guide.

Fines and risks if your listing doesn't match your registration status

The real risk for an owner has never depended as much on the NRUA as on the consistency between the published listing and the property's actual tourism and planning authorisation. The authorities have shown they can cross-check data: in 2026, the Ministry of Housing identified more than 86,000 listings without a valid registration number, with an expired licence, or in breach of zoning rules, and ordered platforms to remove them within 48 hours. The Ministry of Consumer Affairs, for its part, fined Airbnb €64 million after finding more than 65,000 unlawful listings.

These actions are based on tourism and consumer-protection rules, not on the annulled registration procedure, so the Supreme Court judgment does not reduce this risk. This point is covered in more detail in our guide to Airbnb sanctions and fines.

Important:

The end of the NRUA is not the same as "anything goes". A listing can still be taken down for lacking a regional licence, for breaching planning rules, or for being incompatible with the horizontal-property regime, regardless of whether the State number is no longer required.

What to do if this affects you

The right course of action depends on where each owner stood when the judgment was handed down. It is worth distinguishing several scenarios:

  • If you already obtained the NRUA: the number is no longer required, but there is no need to cancel it; what matters is checking that you hold the corresponding regional licence or registration.
  • If you had a pending application: the annulled State procedure can no longer be processed or required as a condition for advertising the accommodation.
  • If your NRUA application was refused: it is worth checking whether that refusal was based on a requirement that has since been annulled, and assessing whether it still has any practical effect now that the procedure itself has disappeared.
  • If your listing was removed or you received an administrative notice: you need to identify whether the reason was the lack of an NRUA — which today would have no legal basis — or a different, tourism or planning, breach that remains fully enforceable.

In every case, the defence against a penalty procedure follows the ordinary route: submissions during the investigation stage, an administrative appeal against the decision and, where applicable, judicial review once the administrative route is exhausted. Deadlines are strict, so it is worth acting as soon as any notice is received.

Frequently asked questions

Does the Single Rental Registry (NRUA) still exist in 2026?

Not as a mandatory State procedure. Supreme Court Judgment 620/2026 declared the Single Rental Registry procedure void for lack of State competence.

I already obtained my NRUA number — what should I do now?

Check that you hold the corresponding regional licence or registration, which is the title that actually authorises the activity, regardless of what happens to the State number.

Are platforms still required to share data with the authorities?

Yes. The Digital Single Window for Rentals and platforms' data-transmission obligations remain in force under Regulation (EU) 2024/1028.

What risk do I run if my listing doesn't match my regional licence?

The risk of the listing being taken down and of a penalty procedure remains, now based on regional and municipal tourism and planning rules rather than on the annulled State registry.
